VAPORIZER FQR HYDRCARBON-LIGHTS.

Application filed February 5, 1919.

To all whom t may concern:

Be it known that I, ADoLrH G. KAUEMAN, a citizen of the United States, residing at New York, in the county and State of New York, have invented a new and useful Va* porizer for IiIydrocarbon-Lights, of which the following is a specification.

This invention relates to lamps, or lights in which a hydrocarbon fluid is vaporized, and the vapor is used as a fuel in producing the light; and the object of the invention is to provide a vaporizer filler in which: 1, the fluid will be vaporized in such a way as to give a more uniform light; 9., prevent clogging; 3, the vaporizer filler will have a uniform thickness; 4, the vaporizer will be uniform in length; 5, clogging of inlet will be prevented; 6, parts will be more easily assembled; and, 7, the vaporizer filler can be more easily removed from the vaporizing tube. n

The invention is illustrated in the accompanying drawing, in which- Figure 1, is an elevation, partly in section, of a vaporizer filler, and cooperating parts, constructed in accordance with my invention.

Fig. 2, is an elevation, mostly in section, of a modified form of vaporizer filler, and,

F ig. 8, is a similar view of another modified form of vaporizer filler.

In the drawing similar numerals of reference refer to the saine parts in each of the views.

In the drawing my vaporizer filler 4 is shown mounted in a vaporizer tube 5 in a manner so that a space 6, 6 is left between the inner wall of the tube 5 and the outer surface of the Vaporizer filler 4.

The vaporizer filler 4 is preferably made of asbestos owing to the fact that it is porous, and will not burn. Any suitable material would answer the saine purpose, but in any event the material if loose and porous would have to be arranged and held in such a manner that it would be substantially uniform in thickness throughout its length.

In making the vaporizer filler I prefer to use arod 7 the lower end of which is provided with a curved portion 8, the end of which is adapted to engage the wall 9, of the piece 10, provided with the screwthreaded part 11 adapted to be fastened in a suitable part of the lamp, as will be under- Specication of Letters Patent.

stood; and the part 11 is provided with a passageway 12 which leads to the vapori'zer filler 4, as clearly shown in Fig. 1. The curved part 8 of the rod 7 is so proportioned in length that the vaporizer filler is held free from the inlet passageway 11, as clearly shown, so that the hydrocarbon fluid to be vaporized will always be free to flow into the vaporizing tube 5, as will be clear.

The drawing shows the usual nozzle 13 in the top of the vaporizing tube 5; the wire gauze 14 in the top of the tube above the vaporizer; and the preheating cup, or startin@ device 15.

Ihe operation will'be readily understood from the foregoing description. The hydrocarbon Huid is admitted to the vaporizer through the passageway 11; and as the same enters the asbestos vaporizer filler it is carried upward and vaporized; -and as it is sporized the vapor is free to rise through the space 6 to the top of the vaporizing tube, where it may pass out through the nozzle 13, for use, as will be understood.

In forming the vaporizer filler shown in Fig. 1, I glue, or cement the asbestos on the rod 7 so that the asbestos will be uniform in thickness throughout its length. As the asbestos is fastened to the rod 7 there is no danger 'of sagging, or bunching and thereby filling up the space 6 so that the gas formed will not have a clear passaOeway to the nozzle, as will be clear.y At Jlie saine time, as the asbestos is fastened to the rod 7 it can be pressed into proper shape after being mounted on the rod so that it will be uniform in thickness throughout its length. There is a further advantage in having the asbestos fastened to the rod as thereby the angled, or curved part 8 of the rod will always hold the asbestos at a fixed distance from the passageway 11, which would not be the case if the asbestos was free to slide down the rod 7, as will be clear.

A further advantage in making the vaporizer filler in this way lies in the fact that, as the heat is applied to the asbestos through the vaporizer tube 5, all parts of the outer wall of the vaporizer ller will be at a uniform distance from the tube, which would not be the case where the asbestos is allowed to sag, and forrn bunches, as will be clear.

By usino" asbestos for the vaporizer filler a very soft, fibrous vaporizer filler is provided in which the hydrocarbon iuid will be readily vaporized Without' any danger Whatever of clogging; and by fastening it against longitudinal movement on the core with the outer surface along the core completely exposed, a uniform vaporizer filler is provided With the exterior surface entirely `free to function as a vaporizer Eller. Thus a vaporizer ller is provided Which is completely protected from bunching, or clogging, and Without interfering With the exterior surface.

It Will thus be seen that by forming the vaporizer filler out of fibrous, porous material glued, or cemented to a fixed rod I provide a construction in Which a much more desirable device is provided, and one Which Will operate With greater certainty. I also provide a device which can be assembled much more easily, and one in which the vaporizer can be removed from the vaporizer tube very easily When desired.

While I have described the asbestos as being glued on, or cemented to the central rod, there are various other Ways in Which a uniform vaporizer could be formed. I have illustrated two of these Ways.

In Fig 2 I have shown a rigid part Within the asbestos 4', and the asbestos is held in position on this rigid part With Wires, or cords 16 and 17. In this construction I may use a loop 18 for the ready Withdrawal of the vaporizer filler from the tube, as Will be clear. It is evident, also, that the angled part 8 could be formed into a loop Without departing from the spirit of my invention.

In Fig. 3, the asbestos Lla is mounted on a rigid part 7a, Which does not extend entirely to either end of the vaporizer; and by using a tyingwire 19, With an extension 2() the vaporizer may be held free from the inlet passageway, as Will be understood.

The upper part of the asbestos may be rigidly held in place With a Wire, or cord 21.

It Will thus be seen that I have provided a simple and eiiicient vaporizer With numer ous advantages by providing means to hold the vaporizing material at a uniform distance from the vaporizing tube throughout its length; by providing means to prevent sagging, or bunching; and by providing means to hold thevaporizerller from the inlet. The construction makes a much more efficient lamp; and the hydrocarbon is vaporized much more efficiently and satisfactorily by having the asbestos held at a uniform distance from the inner Wall of the vaporizing tube.

, I claim: f

1. A vaporizer filler composed of an outer wall of fibrous material and an inner core of rigid material, said fibrous material being held on said rigid material with fastening means between the fibrous material and the core in a manner whereby longitudinal movement of the brous material relative to the rigid material is prevented, and the ex terior of the fibrous material is completely exposed. Y

2. A vaporizer filler for a hydrocarbon light comprising a cylinder of asbestos of substantially uniform thickness cemented to a core of rigid material, said coie of rigid material ht ving a projection adapted to hold the asbestos free from the Wall which said projection engages. Y

3. A vaporizer filler comprising a core of rigid material, and a cyindrical portion of fibrous material cemented lto said core in a manner whereby the said fibrous material is held substantially uniform in thickness throughout its length.
